Thread: cash drawer

hi everyone,

i have 1 question

how to open cash drawer with java?

I use a usb printer to open a Cash Drawer. connected to the pc via usb

how to open a Cash Drawer at the time of printing?

it is the source code

package testConn;
 
import javax.comm.*;
import java.util.*;
 
/** Check each port to see if it is open. **/
public class openPort {
 
  public static void main (String [] args) {
      Enumeration port_list = CommPortIdentifier.getPortIdentifiers ();
 
      while (port_list.hasMoreElements ()) {                                                            >>> [B]this process in the past, why did not you?[/B]
          // Get the list of ports
          CommPortIdentifier port_id =
                  (CommPortIdentifier) port_list.nextElement ();
 
          // Find each ports type and name
          if (port_id.getPortType () == CommPortIdentifier.PORT_SERIAL)
          {
              System.out.println ("Serial port: " + port_id.getName ());
          }
          else if (port_id.getPortType () == CommPortIdentifier.PORT_PARALLEL)
          {
              System.out.println ("Parallel port: " + port_id.getName ());
          } else
              System.out.println ("Other port: " + port_id.getName ());
 
          // Attempt to open it
          try {
              CommPort port = port_id.open ("PortListOpen",20);
              System.out.println ("  Opened successfully");
              port.close ();
          }
          catch  (PortInUseException pe)
          {
              System.out.println ("  Open failed");
              String owner_name = port_id.getCurrentOwner ();
              if (owner_name == null)
                  System.out.println ("  Port Owned by unidentified app");
              else
                  // The owner name not returned correctly unless it is
                  // a Java program.
                  System.out.println ("  " + owner_name);
          }
     }
  } //main
} // PortListOpen

I was able to open a Cash Drawer. code was to display the text into line displays
and I have just completed.

thanks

This command to the API javax.comm :

package testConn;

import javax.comm.*;
import java.util.*;

/** Check each port to see if it is open. **/
public class openPort {

public static void main (String [] args) {
Enumeration port_list = CommPortIdentifier.getPortIdentifiers ();

while (port_list.hasMoreElements ()) { //This part in the diving, why not you?
// Get the list of ports
CommPortIdentifier port_id =
(CommPortIdentifier) port_list.nextElement ();

// Find each ports type and name
if (port_id.getPortType () == CommPortIdentifier.PORT_SERIAL)
{
System.out.println ("Serial port: " + port_id.getName ());
}
else if (port_id.getPortType () == CommPortIdentifier.PORT_PARALLEL)
{
System.out.println ("Parallel port: " + port_id.getName ());
} else
System.out.println ("Other port: " + port_id.getName ());

// Attempt to open it
try {
CommPort port = port_id.open ("PortListOpen",20);
System.out.println (" Opened successfully");
port.close ();
}
catch (PortInUseException pe)
{
System.out.println (" Open failed");
String owner_name = port_id.getCurrentOwner ();
if (owner_name == null)
System.out.println (" Port Owned by unidentified app");
else
// The owner name not returned correctly unless it is
// a Java program.
System.out.println (" " + owner_name);
}
}
} //main
} // PortListOpen
